When I consider your heavens,
the work of your fingers,
the moon and the stars,
which you have set in place,
what is mankind that you are mindful of them,
human beings that you care for them?
Psalm 8:3-4 (NIV)

Years ago I purchased my first scope from a big box store like many others and after some time was discouraged by the lack of quality. I was busy, so lost interest in pursuing it further. It was this 4.5 inch Meade reflector on an Alt/Az Go To mount.

Then a few years ago my brother in law gave me this Orion 4.5 inch reflector on a basic manual Equatorial mount he got from a client of his. After replacing a few needed parts I started to get enthused again and had to learn how to operate a manual EQ mount.

Once I retired, it was time to get more serious and I started learning all I could about Astronomy. I got an Orion XTg 10 inch Dobsonian mount GoTo scope. It's a great visual scope, I liked being able to find Deep Sky objects and planets.
254mm primary mirror 1200mm focal length f/4.7 focal ratio |

My desire now is to be able to photograph the objects I like to view, so I upgraded again to this Explore Scientific Maksutov-Newtonian. It has a meniscus correct lens at the front, a spherical primary mirror and elliptical flat secondary. This gives a flat field, coma free, color aberration free, and no star spikes from secondary mirror support veins.
152 mm mirror 731mm focal length f/4.8 focal ratio I use a Canon T3i for the imaging camera, a ZWO 120MC for guide camera which doubles as a planetary camera on the Dobsonian. The scope is mounted on a Celestron AVX equatorial mount. |
